Questions:
Is it a NOS cable or a modern "will fit" part? It's worth noting that F15 is listed as using *C101W-2275 cables and F15A *C01Q-2275A in case you ended up with the "wrong" part. I don't know the difference between the two cables. LWD parts show a cable tagged with the "correct" part number https://www.lwdparts.com/product/cable-handbrake-f15/ They also list the F15A cable and might be willing to measure length differences (sheath and overall) if asked.
Is the cable fully seating in the holding bracket on the backing plate? (and at the other end?)
Would it be better to take some (but less) off both ends of the sheath? You see less rust than I do but it might prevent formation of a rust ridge in the backing plate bracket that could block future removal.

Default F15 or F15-A handbrake cable?

Hi Tony,

Following on from Grant's comments if there is a major difference in lengths between an F15 And an F15-A handbrake cable I can at least confirm what is the F15-A cable length which may be of help.

The outer conduit is 39-3/4" long and the inner cable is 52-1/4" long giving a difference in the two lengths of 12-1/2"

I am very sure these measurements are accurate as they came off two NOS cables I bought along with the NOS backing plates that they were attached to. I took these measurement a long time ago in case I ever had to replace a cable. They work perfectly on my F15-A (and will be even better when I bend up the clips from the dimensions and photos you supplied!)

Hope this may be of some help.

Cheers,

I don't normally like to cast doubt on field measurements of original parts....but....
Parts list F15A-01 gives a length of 51-3/4 for part *C01Q-2275A (cable-hand brake-assembly),
Parts list F15-01 doesn't give a length for *C101W-2275,
Neither manual gives alternate numbers for earlier or later production.
The same part numbers and length notes appear in the earlier parts lists that cover all models.
I'm puzzled as when I was shortening a pair of *C01Q-2275B cables (originally 86 inches long) to recreate *C01Q-2275A cables for the 15cwt GS trailer I thought the measurements needed to be nearer those Jacques gave than the "official" version.

Default Handbrake cable measurements

Hi Grant,

I agree, field measurements can be misleading however it all depends on where you are taking the measurements from versus what the guy putting together the parts manual measures, or the second or third hand measurements he receives.

My measurements were taken from the ends of the outer conduit at the end of the larger diameter sleeves. In the case of the inner cable, the measurements were from the outer end of the ball to the end of the threaded rod on the equalizer side. If someone only measured the exposed cable a different result would be obtained.

The cables were NOS, perfect shape, never kinked, and I compared both cables and obtained the same results. When installed, everything worked perfectly as intended.

If you think about it, the only critical measurement is the difference between the inner cable and outer conduit. The conduit could be 2, 4, 6 inches longer but as long as the inner cable is 12-1/2" longer the system will work just fine.

The parts manual is a great source of info but as I have found out there are a number of inconsistencies throughout. Looks like you may have found the same thing in regard to the specified measurement with your trailer cables.

In using a parts manual, one must keep an open mind and accept that it may not be gospel.

Cheers,

Default Outstanding

Grant and Jacques,

My sincere thanks to you both. Very, very helpful discussion.

I will have another crack tomorrow and get back with my findings.

Sent an email to LWD parts. Hopefully they will get back to me as well.

Default F15 handbrake cable- Conduit support, final thought

Hi Tony,

Glad to be of some help.

Just as a final thought on the subject; assuming 12-1/2" is the difference in the lengths for both F15 and F15-A cables the only other thing that could affect the cable pulling on the brake shoes would be the position of the Support- Brake Conduit, part Nos. 01T 2501 (right side) and 01T 2502 (left side) in the case of a F15-A. I am assuming the F15 truck uses the same part but that could be a wrong assumption.

If these are bent, or modified, the distance to the equalizer arms will be different to the designed length perhaps causing the inner cable to be "pulled" even when when the handbrake lever is fully off.

I have attached a photo of the setup of the handbrake equalizer and the conduit supports on my F15-A which may help you and others.

Cheers,

Default well well

How about this to throw a spanner in the works.

Cable is 43 and 1/2 inches long.

Outer conduit is 33 inches long.

Interesting to note the outer conduit length is identical to the old ones I pulled out.

The inner cable appears to be slightly longer though on the old cables. It is a bit difficult to tell because both cables had snapped at the end that attaches to the equalizer arms.
